I'm disappointed that HP all-in-one did not accept HP cartridges. Problem is printer hardware faulty but HP won't supply free parts. Cost of parts is greater than cost of new machine. It's hard to prove if machine was purposefully disabled electronically to create new sales. Add more to the landfill!!
Purchased the wrong ink. Opened box before I realized. Don't know if it's returnable. Was going by previous purchase made for former printer based on info on Staples website.
